Hi, and thank you in advance for any help you can give: We just had our roof replaced, but the ice and water shield failed and water is leaking into the plywood under it. The problem is that the roof is made of 40+ year-old SIP's with old, crunchy, water-absorbent foam. The roofer is coming back out to completely demo the job, re-ice/water shield, and then re-install the roof next spring, but we've got at least 6 months until they can re-do it. The house looks a bit like this one (only nowhere near as fancy): http://www.deltechomes.com. It was built in the mid-1970's...and has had no roof problems to date, except for some rotting at the dutch gutters (which were badly designed from the start). I'm wondering: what should I do right now to try to save the SIP's? I don't have the skills to be able to tarp it and the roofer says they can't come back to tarp for several days...and it's been raining on and off (we live in the Northwest). Also: how will I be able to test the SIP's to make sure they haven't been ruined? Do I need to drill holes all over the place from the inside and use my new hygrometer to test everything? At what point should I ask them to replace everything in the roof, SIP-wise? (This would be unbelievably complicated because all of the interior walls are fastened to the roof.) They've only agreed to completely re-do the roofing job at this point, but I don't want to let them off the hook if they've created a big wet, fungus-growing sponge over our heads. Also, if the roof is waterlogged, is it in danger of collapsing? I've heard in the past that the more weight that is added to this type of roof will only make it stronger...but clearly, I'm not a roofer! Thank you for any light you can shed on this!

by your description, I'm not so sure you even have a SIPs roof
EPS is closed cell foam and does not absorb water , I suspect you simply have a conventional framed roof with plywood and sprayed foam to the underside
is there anyway you can post pictures?
